JERSEY, A CORPORATION OF PRESS FOR USE IN THE IEANUFACTURE OF BOOTS AND SHOES.

Application filed March 19, 1919. Serial N0. 283,609.

To a l whom it may concern:

Be it known that I, Enasrus l' l. VVINKLEY, a citizen of the United States, residing at Lynn. in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Presses for Use in the Manufacture of Boots and Shoes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to presses for use in the manufacture of boots and shoes, and it has particular reference to such presses as are employed for maintaining pressure while the paste is drying or setting, upon artlcles of superposed freshly pasted layers, such as built-up leather heel sections, veneered soles, pasted counters, boxes, etc.

One of the objects of the invention is to provide a press of the above indicated class, which shall be simple and inexpensive in construction; effective, reliable and expeditious in operation, and which shall be particularly adapted to subject the articles operated upon to individual and uniformly distributed pressures of predetermined amounts.

Another object of the invention is toprovide a press of this general type which, without adjustments, shall be capable of operating upon a variety of classes of multilayer articles of different shapes and forms.

Another object of the invention is to provide a press that shall be especially adapted to yieldingly conform to the configuration or contour of the laminated articles being pressed in such manner as to hold the edges of the component layers thereof under pres-- sure so as to insure firm and close edge joints.

A. further object of the invention is to provide a press that shall require a minimum amount of skill and attention during its operation, and more particularly a continuously operated press of such form that the articles to be pressed may be loaded into the press without the exercise of care respecting either the positions of the articles or the operating conditions of the press itself.

- superposed relation.

With these and other objects in view, the features of theinventlon comprises certain constructions, arrangements, and combinations of parts hereinafter described and is furnished with a main shaft 10 which extends through and is journaled in standards 12, secured to the base of the machine. Said shaft 10 is driven by. a worm wheel 14 secured thereto, which is connected through suitable speed reducing gearing to a worm 16 carried by a driving shaft 18. This driving shaft is journaled in the frame of the machine and is provided with fast and loose belt pulleys 20. 1

The main shaft 10 carries a pulley 22 of relatively large diameter. A pair of belts 24 and 26 extend around the pulley 22 in The, inner belt 24 is guided and tightly held about the pulley 22 by a guide pulley 28. This guide pulley is spaced from the pulley 22 and is journaled on a shaft 30 which is supported at its ends by side frames 32 on opposite sides of the pulley 22. The outer belt 26 is guided and maintained under tension by a tension pulley 34 which is spaced from the guide pulley 28 and is journaled on a shaft 36, the ends of which shaft extend through a yoke 38 that is pivoted at its lower end on a stud 40 at the base of the machine. The pulley 34 is urged outwardly to maintain the belt 26 under tension by coiled springs 42 which act through rods 44. The rods 44 are socured at their outer ends to blocks 45 fixed to opposite ends of the shaft 36 and the inner ends of the rods extend through and are guided by blocks 50 pivoted upon pins 52 projecting from the standards 12 and the side frames 32. The springs 42 are coiled about sleeves 54 on the rods 44 and are interposed between collars 56 at the outer ends pulley28are so, constructed and arranged though the articles varyin height.

that thelower stretch 60 of the outer belt is substantially in a horizontal plane and the lower stretch of the belt 241: is at a slight angle thereto, which arrangement of the lower stretches ofthe belts terms; a feed opening through which the articles may be presented to the press. This permits the blocks of liftsor other articles to be continuously fed to or placed upon the lower stretch of the belt 26 and as they are being fed thereby to the pulley 22-, the lower stretches ofthe two belts cooperate to. applya gradually increasing pressure thereto. The outer belt 26 is sutiic'iently flexible so that asa plurality of articles are fed about the pulley 22, the be ts and pulley cooperate to apply a uniform pressure thereto cven The pulley 22-is of such diameter and is driven at such speed that when the articles reach thefupper stretches of the belts, the paste which secures the layers together. is prop erly set. The: upper stretches of the belts are so arranged as to form discharge openings through which the articles that have been acted upon by the: press are allowed to.

. drop by gravity into. a suitable chute 62 which conducts them from the press. This chute issecur'ed byboltsla to the ends of thesidexiirarnes 82. -Means are provided'for removing the articles from. the upper stretches of the belts and conducting; them into the chute in case the blocks should ad-. here to the surfaces of the belts. means comprise strippers and 5.6: that are pivoted at 68 on the chute 62 and are respectively pressed toward the belts by means of coiled springs 70. i
